I'm using the newest tip. I have the CoreAudio sdk downloaded.
When i try to compile the audio plugin demo or the audio plugin skeleton that is created by introjucer i get the following:
ld: 287 duplicate symbols for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
this is preceeded by by lots of stuff like this:
duplicate symbol __ZTI15MusicDeviceBase in: /Users/alexandergustafson/Library/Developer/Xcode/DerivedData/DiauproPlugin-hdmzjrfjzaedhmcgysczmsvdwhfd/Build/Intermediates/DiauproPlugin.build/Debug/DiauproPlugin.build/Objects-normal/x86_64/MusicDeviceBase-289FFFAA4B957B80.o /Users/alexandergustafson/Library/Developer/Xcode/DerivedData/DiauproPlugin-hdmzjrfjzaedhmcgysczmsvdwhfd/Build/Intermediates/DiauproPlugin.build/Debug/DiauproPlugin.build/Objects-normal/x86_64/MusicDeviceBase-468F86E0558BD178.o
compiling VST and VST3 without AU active works fine.
